Supervolcanoes ripped up early Mars Mars may have had giant explosive volcanoes in its ancient past that spewed billions upon billions of tonnes of rock and ash into the sky. Vast areas of collapsed ground in a region of the planet called Arabia Terra are their likely remains, believe Joe Michalski a...

Northern Mars Landscape Actively Changing Sand dunes in a vast area of northern Mars long thought to be frozen in time are changing with both sudden and gradual motions, according to research using images from a NASA orbiter. These dune fields cover an area the size of Texas in a band around the planet...

Scientists recommend destination for roving science laboratory 'Curiosity'. Gale Crater, a 150-kilometre wide depression named after an Australian banker-turned-amateur astronomer, has emerged as the preferred destination for the next spacecraft to set wheels on Mars. The proposed landi...

NASA Probe Counts Space Rock Impacts on Mars Scientists using images from NASA's Mars Reconnaissance Orbiter (MRO) have estimated that the planet is bombarded by more than 200 small asteroids or bits of comets per year forming craters at least 3.9 meters across. Researchers have identified 248 ne...

Explosive crater twins on Mars Dramatic underground explosions, perhaps involving ice, are responsible for the pits inside these two large martian impact craters, imaged by ESA's Mars Express on 4 January. The 'twin' craters are in the Thaumasia Planum region, a large plateau that lies immediat...

The International Astronomical Union (IAU) has approved a new name for a valley feature on Mars. Farah Vallis for a 76.37-km-wide Martian vallis located at -6.03°, 136.8°. The feature was named after the Farah river (Persian Farah Rud) in Afghanistan.

Aeolis Mons, formerly Mount Sharp, is a mountain in the center of Gale Crater on the planet Mars. The mountain is located at 5.4°S 137.8°E and rises 5.5 km (18,000 ft) high. Aeolis Palus is the official name of the crater floor plain between the northern wall of Gale Crater and the northern foothills of...

The International Astronomical Union (IAU) has approved a new name for a crater on Mars. Farim for a 3.92-km-wide Martian crater located at -44.31°, 139.28°. The feature was named after a town in the Republic of Guinea-Bissau.

The International Astronomical Union (IAU) has approved a new name for a domical mountain on Mars. Nia Tholus for a 34.01-km-wide Martian tholus (small domical mountain or hill) located at -6.59°, 285.05°. The feature was named after the classical albedo feature name.

The International Astronomical Union (IAU) has approved a new name for a sulci on Mars. Candor Sulci for a 73.36-km-wide Martian sulci (furrow or fissure) located at -4.92°, 283.15°. The feature was named after a classical albedo feature name.

Buried Mars River Channel Reveals Evidence of Relatively Recent Megaflooding Evidence of a megaflood on Mars - a surprisingly recent one that cut a 966-kilometer river channel into the planet - has been detected by radar from an orbiting satellite. Scientists have known for some time about the exi...

The International Astronomical Union (IAU) has approved a new name for a valley on Mars. Tana Vallis for a 56.51-km-wide Martian valley located at 4.78°, 332.11°. The feature was named after a river in Kenya.

The International Astronomical Union (IAU) has approved new names for two features on Mars. Aonia Tholus for a 53.69-km-wide Martian tholus located at -59.04°, 279.96°. The feature was named in honour of the classical albedo feature name. Aonia Mons for a 27.07-km-wide Martian mounta...

ESA's Mars Express took a high-resolution stereo i​mage on 13 January of the southeast corner of the ​Amenthes Planum region on Mars, near to Palos crat​er and the mouth of a well-known sinuous valley, T​into Vallis. [url=http://www.esa.int/Our_Activit​ies/Space_Science/At_the_mouth_of_the...
